Cisco Nexus N3K 3000 Switches - Refurbished, Used, and New

The Cisco Nexus N3K series delivers low-latency, high-performance switching built for the most demanding data center environments. These fixed 1RU switches provide top-of-rack access with ultra-low latency across both Layer 2 and Layer 3 traffic, making them an excellent choice for high-frequency trading, high-performance computing, and cloud-scale deployments where speed is critical.

Available in models with 48 ports of 1/10G plus high-bandwidth uplinks, the Nexus N3K family also includes options with 40G and multigigabit interfaces. These switches run NX-OS, offering consistency across the Nexus portfolio, while supporting automation, programmability, and overlay technologies like VXLAN for flexible and scalable fabric architectures.

The N3K platform is engineered for reliability. With hot-swappable power supplies and fans, as well as shared buffer designs that absorb microbursts, these switches maintain continuous performance under heavy workloads. Advanced QoS and congestion management ensure that critical applications receive the necessary resources, even during traffic spikes.
